Summary of the invention:
For solving the deficiency of the described present various bicycle anti-theft techniques of background technology, the invention provides a kind of built-in lock that pins the bicycle axis, can contain effectively that the thief steals car, for solving the problem of this technology existence at present, the technical solution used in the present invention is: the part overstriking between two retaining bowls of the axis (see figure 1) of existing bicycle (1), and a week of thickened portion establishing several teeth or beating several holes, for pinning axis in dead bolt insertion between cog or the hole, it can not be rotated, do not tear open not get off yet, reached the purpose of pinning axis.Because this lock is to have pinned axis with the method for built-in lock, as long as disclosing the axis of not unblanking from key hole, the thief just not changes, this car has just lost power and can't use, unless the car thigh frame steel pipe of dress lock is cut the lock of dismantling, steel pipe is restored to the original state weld good could the use again, this has just stayed tangible weld mark onboard, and originally on the car spray paint, pictorial trademark all is damaged, the thief can't restore former lacquer, makes other people know that at a glance this car is a stolen car, thereby has contained that the thief steals car.This lock is made up of following accessory and structure: (name in the following bracket is called later abbreviation title) 1, axis: with the axle that pedal is ined succession, this axle rotates with pedal under the power of pedaling of pin.2, thickened portion: the part of on axis, setting up overstriking, be in order to establish several teeth or several hole in a week of thickened portion, for pinning axis in dead bolt insertion between cog and the hole, lock Che Shiwei makes things convenient for dead bolt to insert, we adopt the mode of tooth, prevent to pull down axis when pinning car, and (tooth is stifled) blocked at the two ends of tooth, be named (groove tooth) because of this tooth exactly likes flute profile, the degree of depth of its teeth groove must not surpass thickened portion.3, axle sleeve: the axle sleeve of axis is positioned at the corresponding position of groove tooth makes a call to a hole (trepanning), pass this hole insertion groove between cog for dead bolt.4, guide pipe: it is positioned at the communication port of any steel pipe that axle sleeve links to each other with two steel pipes of car skeleton (steel pipe), there is a hole (pilot hole) that diameter is identical with trepanning the centre of guide pipe, the shape and size of its cylindrical should match with shape, the size in the steel pipe, effect is that dead bolt is controlled at the position of aiming at trepanning all the time, the arc of guide pipe lower surface should match with the cylindrical of axle sleeve, for guide pipe and axle sleeve welding back smooth welded seam, outer one circle of guide pipe lower end is smash the angle.5, dead bolt: the lower end of dead bolt is the part of the insertion groove tooth of 9mm length up, up be the part of cover return spring (return spring) again, the upper end of return spring is a stage clip iron, the effect of return spring is, heads on stage clip iron with opening of return spring and rise when unblanking, and makes dead bolt withdraw from groove tooth return and opens state at lock, its effect of stage clip iron is, when lock lock with the moving down of dead bolt and stage clip iron, compression return spring, the elastic force when this return spring opens are the twices of required drive when unblanking.The upper end of stage clip iron is a shaft portion, its effect is to make tapered end be elevated to certain position unlocking person is not bent over, the first half of connecting rod has a top spring iron, be with a joint buffer spring on the connecting rod of spring iron upper end, top, the top of end link on the buffer spring, there is a detent rail to be fixed on the inwall of steel pipe, top spring iron is risen, because the detent rail of buffer spring upper end is fixed on the steel pipe, so compressed while of buffer spring, alleviated the impulsive force of return spring, other accessory that can prevent to lock damage and noise excessive, and the elastic force of buffer spring when compressing fully is slightly less than the elastic force of return spring when opening, buffer spring is compressed fully and is as the criterion when opening with return spring, the square groove on connecting rod top is to be connected with the extension iron phase of bar tooth lower end, and check screw is used on the screw hole.6, detent rail: buffer spring is compressed under the lock opening, and it is concordant with the guide pipe lower end that the end of dead bolt is positioned at, and for preventing the rotation of dead bolt and bar tooth, the side on the connecting rod combines with the gap of detent rail in lock work.7, bar tooth: because of being close to the steel pipe inwall in the back side of bar tooth, dead bolt then is in the centre in the steel pipe, so having an extension iron to inlay with the square groove on dead bolt top, the lower end of bar tooth is connected, be in order to prevent that the bar tooth from rotating at work, the work that matches with gear of bar tooth, its effect is under gear rotates with lock core, the bar tooth is moved up and down and drives dead bolt with moving.As shown in Figure 8, return spring is at open state when lock is opened, and buffer spring is the state that compresses fully, and what pressing the buffer spring upper end is detent rail, this detent rail height at this moment is exactly the position that is fixed on the steel pipe inwall, and this moment, the end of dead bolt was concordant with the guide pipe lower end.As shown in Figure 9, when the lock locking-in state, dead bolt stretches out guide pipe, and return spring is compressed by stage clip iron, and buffer spring opens and the residing state of detent rail.10, gear: it is assemblied on the lock core of tapered end front end, is in the center of
